APPENDIX VI
LETTER OF TANSAR TO THE KING OF TABARISTAN.
Christensen, by the following reasoning, comes to the conclusion, that it was written somewhere between 557 and 570.
Among the sources of our knowledge of the Sasanian institutions, one of the most important is the letter of Tansar to the king of Tabaristan published and translated by Darmesteter in the Journal Asiatique (1894). The information which it gives on points where we can verify it is so exact that we cannot doubt that the letter was composed in the time of the Sasanians. On the other hand, on the first reading of the epistle I formed the impression that it was a literary fiction dating from the time of Khusro when the tradition made of Ardeshir the model of political sagacity and the founder of the entire organisation of the empire. The letter impressed me as a historical, theological, political and moral dissertation which in the shape of a correspondence between the grand Herbed Tansar and the king of Tabaristan, ill-informed regarding the new state of affairs and hesitating to submit himself to Ardeshir, was calculated to instruct contemporaries. It, therefore, fits in with the entire literature of the Andarz type, which was developed under Khusro and the object of it was the moral instruction of the people. A more minute examination has confirmed me in this view and now I think I am able to affirm positively that the letter was composed under Khusro I. Tansar relates that Ardeshir softened the penalties for crimes against the religion. Formerly, "they used to put to death without hesitation those who set aside the religion of the State. But Ardeshir has directed that the accused shall be arrested and shall be catechised during a year and only if that proves of no effect he shall be killed." As a matter of fact, the rigorous ordinance which awarded the punishment of death for apostacy could not have existed before Parsism became with Ardeshir the State religion. The relaxation of punishment, on the other hand, dates from a much later period, when the standpoint of greater humanity began to be prevalent and when it was attempted to give greater authority to these views by attributing them to the celebrated founder of the dynasty. And we can say the same thing with reference to the less severe punishment for crimes committed against the State and in respect of other things mentioned in the letter. Besides, the tolerance in matters religious and the humanity of Khusro I are well-known.
Now let us look at the incident of succession. According to the letter Ardeshir did not like to choose his successor lest the latter should wish for his death. So, he arranged for the succession in the following manner. The king only left in his royal letters a few counsels or instructions to the grand Mobed, the commander-in-chief, and the principal secretary, and after the decease of the king the latter were to proceed to elect a successor from among the royal princes. If they all were not of the same mind the choice should rest with the grand mobed alone. But Aideshir had made a formal notes that he was not going to establish a president thereby, and that "in another age a manner of looking at things different from ours may appear the proper one." In the first place such an arrangement accords ill with the nature of a statesmen like Ardeshir, for we know from Tabari who follows the official chronicle of the times of the Sasanians, that Ardeshir as well as Shapur I and II themselves chose their respective successors. But in the times between Ardeshir II and Kawadh the election of the king was generally in the hands of the noblemen, and the system mentioned by Tansar may well have suited this period and been in harmony with the singular expression ascribed to Ardeshir that the system in question was not a definite one, and that in other periods, other manners might be more convenient. It seems to us that the letter of Tansar was composed at a period when the memory of the system of Ardeshir was still living although it had already been abolished. In other words, it was the time when the kings had gained the power to nominate their successors during their life-time, which brings us to the period between Kawadh and Hormum IV.
The letter makes Ardeshir say "None but the subject kings who do not belong to our House can assume the title of king barring the wardens of the marches of the territory of the Allans and the districts in the west and of Khwarzm." By the oppression 'the warden of the matches' we must understand no doubt the marzbans of the countries established by Khusro.
Finally, the geographical notices permit us to determine in a more exact fashion the time of the origin of the letter…. The letter was consequently, composed after the march of Khusro I towards the East by the destruction of the Hephthahtes, but before the capture of Yemen. that is to say, between 557-570.
Christensen finally notes that Marquart has arrived at the same conclusion, by another way, namely, that the letter is a fiction of the time of Khusro I. (See Eranshahr page 30, note 2).
